To all tvhom it may concern:

Be it known that I, COLUMBUS PHILLIPS, OfMeridian', county ofLauderdale, State of Mississippi, haveinvented certain new and usefulImprovements in Attachments for F eed-Water Injectors, of which thefollow ing is a specification.

My invention relates to attachments for feed-water ln ectors forlocomotive boilers of the general type shown in my United for feed-waterinjectors which can be attached to the boiler of a locomotive preferablyso that the valve through which water is admitted to the boiler will beabove the water inlets when the valve is open, in which also provisionis made for the supply, preferably through the same inlet-valve, offeed-water discharged from a plurality of injectors, and in whichprovision is made for cutting out any one or all of the injectors, atwill. In my patent above referred to means are shown as provided forcutting out both injectors, but such provision necessitates theinterruption of the supply of feed-water to the boiler whenever theinjectors are cut out. By my present invention I am enabled to out outone or more but not necessarily all of the injectors, and

by that means whenever repairs are necessary in an injector or itsconnections, it can be cutout of service without interrupting thefeed-water supply, which is a feature of great practical .ut1ity.Moreover, through employment of means for cutting out the injectors oneby one, Iprovide equipment m a locomotive for producing, at will, awater jet, which may be utilized for extinguishing fires or for otherpurposes about a locomotive for which the avallability of a water jetstitute a partof this application, Figure I is a side elevation, partlyin section, of one and the preferred form of embodiment of my invention,showing one of the feed-water cutoil valves closed, and showing also apreferred form' of lever for actuating the same. Fig. II is atop planview of the subject matter of Fig. I, showing one of the feed-waterpassages of my device in section. Fig. III is a section of a portion ofthe subject matter of Fig. II taken on the line IIIIII thereof, theparts omitted from Fig-II by section being restored and the check-valveand feed-watercut-ofi valve being in elevation. I ig. IV is a viewsimilar to Fig. I showing a modified form of embodiment of my invention,the feed-water controlling valves both being shown in elevation, oneopen and the other closed. Fig. V is a horizontal section on the line VVof Fi IV, all valves being shown in elevation. Fig. VI is a section onthe line VIVI of Fig. V looking toward the feed-water cut-0E valve andshowing one 'of the check-valves open and the other closed, the commoncheckvalve, which is identical with that shown in Fig. I, being open.Fig. VII is a erspec- .tive view of the subjectmatter of Fig. IV,partially in section with all valves omitted and illustrative of thearran ement of the water passages within. the ody or shell shown therem.Fig. VIII is. a detail view illustrating one of the water jetconnections, comprehended, as above specified, as coming within thescope of'my invention.

Referrin to the numerals on the drawings and first to- Figs. I to III-thereof, 1 mdicates the body of shell, which may be of any preferredcontour and relative arrangement of parts. Being adapted as anattachment for a plurality of in ectors, not illustrated, it is shown asprovided with two lateral passa es 2 and 3, respectively, which areconnected directly with injector pipes represented by flange joints 4and 5 secured to the passages 2 and 3, respectively, as by spanner nuts6 and 7, respectively, for whose accommodation any usual or properprovision is made.

The passages 2 and 3 communicate as through parallel diagonally disposedconnectin passages 8 and 9 (see Fig. II) with a sing e main bore 10.

The shell is preferably provided with a flange-base 12, which is securedto a baseplate 13 as by a crown of bolts 14, the baseplate being securedto the boiler-shell 15 as by an annular series of screws 16. Thebaseplate 13 is provided with a bushing 17, which is threaded to theaperture provided for it, and projects downwardly into the interior ofthe hood 18, which depends through .the boiler-plate 15 from thebase-plate 13 with which it is preferably made integral.

The bushing 17 is provided with a valveseat 19 to and from whichreciprocates a check-valve 20, whose stems 21 and 22 work in suitablebearing provided for them in the bushing 17 and hood 18. Lateralapertures 23 in the hood 18 permit communication between the interior ofthe hood and the interior of the boiler. The check-valve is identical infunction and substantially identical, with slight structuralmodifications, in con struction with that shown in my previous patentabove mentioned.

The passages 8 and 9 are closed, respectively, by a cap-plug 27 and avalve-stem uide-plu 28, a In 27 and a plug 28 being iroyided or eac h passage 8 or 9 (see Fig. III

The cap-plugs 27 are located respectively above the vertical portion ofthe bore in the lateral passages 2 and 3, each of which is closed by itsrespective check-valve30, which, provided-:with a guide-apron 31, (seeFig.

III) playsbetween its valve-seat 32 and the cap-p ug 27. A guide-pin 33working in a co-axial aperture 34 in a projection 35 on the top of thevalve 30, serves by cooperation,with the guide-apron 31 to guide the.

valve truly to and from its seat.

The valve-stem guide plug 28 (see Fig. III) is screwed into the shell inco-axial alinement with its branch of the bore 10 thereof. The bore 10within the lower part.

of the shell being common to both of the passages 8 and 9 respectively,as specified, is

divided into branches or bifurcated so as to afiord independentcommunication with said passages.

Each plug 28 carries within a stuffing box having a gland 37 as upon avalve-stem 38, a cut-off valve 39, which works to and from itsvalve-seat 40. Each guide-plug 28 is providedwith a spider or skeletonframe 41, which carries an intcrnallyand externally threaded cylindricalmember 42. The

" external threads thereof are-provided for the accommodation of ajam-nut 43, by which as through arms 44 compressing force -may becommunicated to, the-stufling-box 45 is a depending lever, which isdesigned to lead in practice a position within easy reach of theengineer in his cab and the pitch of the threads upon the valve-stem 38is preferably such as to render the valve 40 operative by rotativemovement of the lever through the smaller part of a circle. No cabbeingillustrated or necessary to be illustrated in the drawings, it is deemedsufficient to indicate the general direction of the sweep of the curveof the valve lever 45, which is shown in Fig. I as broken away.

"With reference to the operation of my device, let it be assumed thatthe valves 40 are both open. Under such conditions a feed-water supplyunder pressure from the injectors is presented through the )ipes 4 and5, respectively. The force behind the feed-water supply afforded by theinjectors through the pipes 4 and 5,'respeetively, lifts the valves 30and passing them enters the bore 10 of the shell, whence it finds egressaround thevalve 2O intohthe boiler. The valve 20 closes under backpressure from the boiler in the manner understood in the art since theissue of my patent above referred to, and the valves 30, aided bygravity, cooperate with it to confine the steam pressure 0 the boiler,save at such times as the flow of feed-water is forcing its way past theseveral valves into the boiler.

If at any time it be desired to cut out any one or more of theinjectors, all that is necessary is to close the valve 39 as by swing ofits lever 45. When that is done, all the avenues of communication on theinjector side of the said valve 39 are 'cut out of service, but withoutinterfering with the operation of the remaining valve or valves 39 ofthe attachment. Consequently, the injector whichcommunicates with thevalve 39 that 'is closed bein cut out, any needed repairs can be madewithout interrupting the supply of feed-water to the boiler whichcontinues to flow around the valve or valves 39 remaining open.

In Figs. IV to VII inclusive of the drawings, I show an injectorattachment operating in accordance with the principle of my invention asabove set forth, but with certain modifications as to details ofconstruction. Proceeding to specify the same, it may be observed thatthe shell, which is indicated by the reference numeral 50 in'thosefigures, may be as to its base and the manner of connecting the same tothe boiler- 'plate 15, substantially identical with the constructionpreviously specified, and does not, therefore, require any additionalspecification. The illustration in the said figures of the base-plate,the elements depending therefrom, and the mode of connecting them withthe boiler-plate 15 are equally applicable also to the matterillustrated in Fig. I.

The shell '50 is provided with lateral passages, which, althoughsubstantially identical with the passages 2 and 3, are designated by thespecial reference numerals 51 and 52. They communicate with feed-watersupply plpes 53 and 54,-respectively, corresponding with the pipes and5. The passage 52 communicates through a check-controlled aperture 56with a chamber 57, and the passage 51 communicates in a like mannerthrough a check-controlled aperture 58 the shell through which the saidcheck valves 60 and 61 are accessible, and bysaid plugs their upwardmovement is limited. The screw-plugs 62 and 63, respectively, correspondsubstantially in every respect to the screw-plugs 27 previouslyspecified, thoughslightly modified in construction by the omission ofthe guide-pins 33, which is avariatlon purely optional andnon-essential.

in respect to either of the set of plugs. The chambers 57 and 59 areseparated from each other by partition walls 65 and 66,. which definebetween them a middle chamber 67 communicating with the main bore of theshell 50. The partition wall 65 is provided with a valve-seat, to andfrom which works a cut-off valve 68. In like manner, the pars titionwall 66 is provided with a valve-seat 69 to and from which works thec'ut-ofi' valve 70. The valves 68 and 70 are pro vided respectivelywith-a threaded valvestem 71, said stems being in each instanceidentical in construction, which working in a valve-guide plug 72through a stufling-box 73, may be 0 erated as by a hand-wheel 74.'

The mode 0 operation is substantially the same as that previouslydescribed and the illustration of one form of embodiment of my inventionmay well serve the purpose for which, in part, it is intended, namely,to-

afford clear explication of the mode of operation of the other partthereof.

75 indicates a pet cock communicating with the inner chamber 67. I

It has been specified that one feature of my invention is to providemeans for de- V riving a jet of water from an injector whenever occasionfor the use of the same arises. Accordingly, having provided for cuttmgout either injector, I provide in the injector pipes 4 and 5respectlvely (see Fig. VIII) a valve-controlledhose connecting pipe 76.Ordinarily the valve 77 thereof is kept closed. If, however, it beopened the feed-v water su plied from the injector connecting therewitwill pass out through the pipe connection and may be distributed in useas through an ordinary nozzle, not necessary to illustrate. The check,which controls the e for cutting-o passage with which the injector-pipeso opened to the atmosphere communicates, may serve to cut ofi backpressure of the boiler, but if preferred, such pressuremay be cut offpositively by the closing of its appropriate cut-ofi valve, for example,either of the valves 30, as shown in Figs. I to III of the drawings, orthe valves 68or 70, v
